WATER QUALITY AND 
MAINTENANCE

GENERAL GUIDELINES FOR WATER QUALITY MAINTENANCE

Maintaining water quality within specific limits will enhance your enjoyment and prolong the life
of the spa. Safe, comfortable and clean spa water is a fairly simple task to achieve, but it does
require regular attention because of the numerous factors that can alter it. There is no one for-
mula to be followed because of the variables, i.e. quality of the water used to fill the spa, water
temperature user load, etc.

Developing a disregard for water maintenance will result in poor soaking conditions, damage
your spa investment and possibly void your warranty.

Spa water maintenance consists of three separate easily developed programs :

1. Sanitizing and maintaining a safe level of sanitizer in the spa water.
2. Balancing the pH and maintaining the recommended mineral content level.
3. Achieving and maintaining water clarity.

SANITIZING

To destroy bacteria and organic compounds in the spa water, a sanitizer must be used
regularly. The use of a bromine floater is recommended. By regulating the amount of
tablets, the amount of time the floater is open, and the length of the filtration cycles,
you can control the amount of bromine in your spa. A bromine residual of 2 to 3 PPM is
generally considered desirable. A two-part bromine system or a granular chlorine
(dichlor) system is also acceptable Sanitizers.

pH CONTROL

pH is a measure of acidity and alkalinity of the spa water. The recommended pH for spa
water is 7.4 to 7.6 ppm. Below 7.0 (considered neutral), the spa water is acidic and can
cause damage to the heating system. Above 7.8 the water is too alkaline and can result
in cloudy water and scale formation on the spa shell, heater, and cover.

IMPORTANT: NEVER USE CHLORINE TABLETS OR LIQUID POOL CHLORINE (TRICHLOR) 
IN YOUR SPA.

This chemical can have an extremely corrosive effect on certain materials in the spa. Also, the
use of liquids, chlorine or acid, are not recommended. Damage caused by use of these 
chemicals, or improper use of any chemical, is not covered under the spa warranty.

OPTIONAL LIGHTNING SERIES WATER PURIFICATION SYSTEM

If you have elected to equip your spa with the ozone water purification system, you will
find that your water stays fresh and clean with significantly less usage of chemical sani-
tizer and you will also be able to go longer between spa draining. Read and follow the
instructions included with your ozone water purification system to determine how to
adjust your chemical usage and filter cycles.
